Overview of Petrol, Diesel & Fuel Oil Testing

Tested by: NABL-accredited partner lab
Regulation: IS 2796, IS 1460, IS 1593
Typical turnaround: 3–5 working days
Sample needed: 1–2 litres in a metal can

Petrol must meet IS 2796 and diesel IS 1460. Since BS-VI fuels were introduced across India in 2020, the sulphur limit for both is 10 mg/kg, and petrol is now blended with ethanol. Industrial fuels such as furnace oil, LDO and LSHS have their own standards for viscosity, sulphur and calorific value.

Fleet operators, transporters, DG set owners, boiler users and fuel traders test fuel to settle quality disputes, detect adulteration with kerosene or solvents, check water contamination in storage tanks, and confirm what they paid for. Engine and fuel-system makers also test fuel during warranty investigations.

5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Density and distillation	Basic identity and adulteration check
Sulphur	BS-VI limit of 10 mg/kg for petrol and diesel
Flash point	Safety in storage and handling
Research octane number	Knock resistance of petrol
Cetane number or index	Ignition quality of diesel
Water and sediment	Contamination in storage tanks
Ethanol content	Blend level in petrol
Viscosity and calorific value	Furnace oil, LDO and other industrial fuels

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Can the test show whether diesel is adulterated?

Density, distillation, flash point and a few other parameters together usually show whether diesel has been mixed with kerosene or solvents. A single parameter on its own is rarely conclusive.

Which standard is the product tested against?

The Indian Standard, international method or buyer specification that fits your purpose. We confirm it with you before the sample goes to the lab, and the report states the method used for each parameter.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
